ROOFING.

To all w/Loni tut lmay concern:

zen ot' the United States, residing at Forest. in the county oi' llardin and State ot Ohio, have invented certain new and uset'ul lmproveinenti in Hootings. of which the 'tol- Alowing a specification, reference being had to the acqnnpanying drawings.

This invention relates to improvements in nietallieroong and more particularly to doulle lock seams or joints for the sections or sheetsI ot' routing made of galvanized sheet irongtiu and other sheet metal.

(hie object of the invention is to provide a rooting ot this character which may be made in sect-ions at ,the factory and readily interlocked and rendered waterproof by the person who lays it and a further object of the invention is to Y provide an eliective means tor 4vsti'engthening the double lock seam or joint-,ofthe rooting sheetsvor sections. i With the above and other objects in view, the invention consists of the novel features ot' construction and the combination and arrangement ot' parts hereinafter fully described and claimed. and illustrated in the accompanying drawings, in which- Figure l is a perspective view ot several of the rooting sections or sheets showing the manner in which they are assembled and interlocked; Fig. Q is a perspective view oi one of said sheets or sections; Fig. 3 is a sectional View through the finished joint or seam and showing the extra locking` niem- `ber or strip; Fig. l is a` detail View ot' the `locking' strip; and Fig. 5 is a detail view showing the manner in which the ends ot' two sheets or sections lnay be overlapped and iuterlocked.

Tn the drawings l denotes one of my improved rooting .sheets or sections. each of which is'uiade from a single piece of galvanized'sheet metal or any other sheetmaterial. These sections may be made ot any length, although preferably niake them sixjieight or ten feet, long. They are shaped at lthe factory, as shown 'more clearly in Fim, that is. one longitudinal edge of each sheet is bent upwardly at right angles, as shown at 2, and then inwardly at right angles, as

lshown at 3, so as to provide an angular flange along said edge. The opposite longi tudinal edge of the sheetA or section l is bent up vardly at right angles, as shown at 4, then outwardly at right angles, as at 5, and

l l then its extremities bent downwardly and Be it known that l, FLo'rn Morie'r'r, a citiinwardly at an angle, as shown at G. Said l lient portions 4. 5, (i provide another angular tlange with a channel formed by the portion t5, which channel is adapted to receive 'the portion 3 on the next adjacent root section, as shown at t in liig. l. itt'ter two sheets are thus assembled the portions 3. 5, t5 are bent downwardly, as shown at Zi in Fig. l, so as to provide an etlcetive double lock seam or joint which will be entirely water prooi. lt is desirable to more securely lock such seanis or joints at intervals throughout their lengths, and this l preferably accornplish hy means of metal strips 7 which are arranged in said joints, as shown more clearly iirFigfB Each of said strips 7 is folded upon itself, as shown at 8, so` as to receivethe portion or iiange 6 and one ot' its ends is 'bent around the tiange 3, then over the tlauge 2 and has its extremity bent et right angles, as shown at 9, under one ofthe sections or sheets 1. The other end of' the strip 7 is bent around the flange 5, then up over the flange `ll` land has its extremity l0 bent downwardly over the'top ledge of the joint. as more clearly shown in Fig. l. It, will be noted that this locking- Strip is bent iu a reverse direction to that ot' the joint or seam and thereby forms an effective lock for the same. l

Where the roof is longer than the section or sheet and it is necessary to place the saine over upon themselves to provide hook flanges ll which are engaged with each other, as shown more clearly in Fig. The ends ot the sections or sheets which arethus 'bent to form the interlocking flanges ll have thc longitudinal or side franges projecting sheets so that they will overlap the correspending longitudinal or side tlanges of the abutting` or adjoining sections.

While the invention is especially adapted for use in making galvanized sheet iron or sheet metal roofing, it will be understood that the sections may be made of tin or other sheet metal or sheet material. It will be :further noted tliatthe sections or sheets may be made at a small cost at the factory so that they may be quickly assembled and interlocked on the roof by simply fitting them into each other and then hammering down the eneaged flanges and then squeezing to- :o gether said flanges.

end to end, their end edges may be folded' beyond the body portions ot the sections or Having thus described the invention what is claimed is:l

The herein described 'roofing comprising a rectangular sheet having one 'of its longitudinal edges bent upwardly and inwardly to provide an upstanding right angular flange having a vertical portion and an inturned horizontal portion, a second rectaiiA gular sheet having one of its longitudinal 'istrip having a horizontal end 9 disposed he 4edges bent to provide an opstanding angiig lar flange having a vertical portion, an outl Wardly projecting horizontal portion and an edge portion folded under said outwardly projecting horizontal portion, thc inwardly projecting horizontal portion of the flange t on the first sheet being adapted to enter beneath the outwardly projecting horizontal l portion and said edge portion on the second sheet, and the engaged horizontal portions i of the two sheets being adapted to be bent downwardly, and a locking and attaching portion 'to engage the outer faces ot the "vertical and horizontal portions of the angulartliiige on the first-sheet` the double fold 8 to receive the edge portion of the iange on the second sheet and adapted to be bent downwardly with the horizontal portions of the flanges of the two sheets, said strip also having the. `free end l0 extending vertically and engagcdwith the outerface of the upright angular portion of the flange on the second sheet, said end l0 being bent over said flange and downwardly in a direction opposite to the 't'olrling ofthe flanges of the vtwo sheets, as and for the purpose set forth.

ln testimony whereof l hereunto affix my signature iii the presence of tvfo witnesses.
